FOUNTAIN-PEN.

SPECIFICATION forming part of Letters Patent -.T.\'l'o. 357,176, dated February 8, 1887. Application tiled September-18, 186. Serial No. 213,872. (No model.)

.T0 a/ZZ whom it may concern:

Be it known that l, ALPnoNso H. COBB, a citizen of the United States, residing at Rockland, in the county ofKnoX and State of Maine, have invented a new and useful Improvement in Fountain-Pens, of which the following is a specification. J

My invention has relation to that class of fountain-pens wherein the holder, constituting a cistern for the inlestlpply, is arranged to receive an ordinary splitnib pen, and is provided with devfices for conveying the ink from the cistern to the pen.

The objects of. lny invention are to simplify the construction, to reduce the number ofparts, to render the feeding device instantaneously adjustable to any style or size of pen. and readily removable for cleansingif the ink becomes thick or clogged.

It consists in the devices illustrated in the accompanying drawings, as hereinafter described and claimed.

In the accompanying drawings,l which are enlarged one diameter in excess of the actual size, Figurel is an elevation, and Fig. 2 a longitudinal central section, of a pen and holder embodying my invention.

The holder A consists of a hollow case, preferably of hard rubber, closed at the upper end and having in the lower end a stopper, B, of the sante material. The lower end ofthe stopper B is a hollow cylinder, in which is inserted a split conical screw-plug, C, retained by being screwed into a recess inthe stopper B, and which, with the inner face vof said cylinder, forms a recess for the reception of the pen D.

- Through the screw-plug C and stopper B is an oritcerunning diagonally from near the center of the pen to the opposite end of the stopper B, close to its outer face. In this oriflee is inserted a slender strip, E, of elastic material-such as rubber, whalebone, or the li k e- Which fits loosely therein, and the ends of which project therefrom in each direction and press, respectively,on"the inner faces of the pen D and holder A. The pressure of the lower end against the pen is slight, and only suftlcient to insure Contact therewith at all times, and it canV be instantly moved in either direction to rest near or remote from the pen-point.

The upper end projects so far beyond the stopper B that the part which rests against theinner face of the holder A is, by friction therewith caused by its o wn tension7 retained in place. Y

In operation, the holderbeing filled with ink and a peu properly placed therein, the strip E is drawn outward to a position near the point of the pen, preferably about one-eighth of an inch therefi om. The ink, by capillary attraction, flows through the oritice around the strip E, and, following it, is conveyed to the penpoiiit.

lt is obvious thatthelipperend ofthe holder A may be closed by a removable cap, and that a solid partition integral with the holder may be substituted for the stopper B without departing from my invention. the essential fea- 1tures ot which are, and which Iclaim- In a fountain-pen ot' the species described, the hollow holder A, forming an ink-cistern,

and having at its lower end a recess for the pen, and between said recess and cistern a partition 'through which is a diagonal orifice in which rests a strip of elastic material. theends of which press, respectively, the inner faces of the pen and cistern, substantially as shown,

and for the purpose specified. 4

In testimony that l claim the foregoing I have hereunto set my hand this 28thV day of August, A. D. 1886.`
